////Least-recently used (LRU) queue device//Demonstrates use of the libczmq API////While this example runs in a single process, that is just to make//it easier to start and stop the example. Each thread has its own//context and conceptually acts as a separate process.//
#include "czmq.h"

//Logic of LRU loop//- Poll backend always, frontend only if 1+ worker ready//- If worker replies, queue worker as ready and forward reply//to client if necessary//- If client requests, pop next worker and send request to it
